The transmission zeros(TZ) of Quasi-elliptic function filter could be placed in any position, so the attenuation out of band is controllable, then a high selection performance could get.
In this paper, the change pattern of the cutting vibration signal during the transient processes and the effect of the parameters of band pass filter on the signal transmission are analyzed.
本文分析了切削振动信号在此过渡过程中的变化规律以及带通滤波器对信号传输过程的影响。

In addition, the stop-band rejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.
